Introduction:

Today, the pneumatic tube transport system (PTS) is used frequently because of its advantages related to timing and speed. However, the impact of various types of PTS on blood components is unknown. The aim of this study was to examine the influence of PTS on the quality of routine blood cell counts, erythrocyte sedimentation, and certain blood coagulation tests.

Materials and methods:

Paired blood samples were obtained from each of 45 human volunteers and evaluated by blood cell count, erythrocyte sedimentation, and several coagulation tests, including prothrombin time (PT) and activated partial thromboplastin time (aPTT). Blood samples were divided into 2 groups: Samples from group 1 were transported to the laboratory via the PTS, and samples from group 2 were transported to the laboratory manually. Both groups were evaluated immediately by the tests listed above.

Results:

The blood sample test results from groups 1 and 2 were evaluated and compared. No statistically significant differences were observed (P = 0.069–0.977).

Conclusion:

The PTS yielded no observable effects on blood cell counts, erythrocyte sedimentation, or PT and aPTT test results. We concluded that the PTS can be used to transport blood samples and yield reliable results for blood cell counts, erythrocyte sedimentation, and several coagulation tests.  相似文献

This article departures from the understanding of environmental sustainable education (ESE) as a political project that consists of dissonant and conflicting voices. The aim of the article is to understand how affection, i.e. bodily sensations, transform into political emotions in teaching and learning settings. The article offers a philosophical and empirically based model called the ‘political moment model’ for analyzing bodily anchored political emotions in teaching and learning of the political dimension. The model was developed in response to an empirical case study where the data were somewhat confusing. In order understand the empirical data, we used parts of Mouffe’s theory of the political and various scholars’ work on political emotions and placed these aspects in a pragmatist standpoint of experience, emotions and meaning making. The model helped to investigate students’ experiences of the political dimension in situations where they experienced affection, i.e. bodily sensation, and emotions in connection with reflections and discussions about how to handle public issues of sustainable development. The article ends with a theoretical discussion of the findings in order to understand the political dimension in teaching and learning activities and to discern possible directions for future research on political moments in ESE.  相似文献

This paper seeks to trace the development of graduate studies in basic sciences in Turkish universities from origins to the present day. The study includes a sketch of the historical background of higher education from its start in medieval madrasahs and Istanbul Darulfunun (The House of Sciences), to the transition into present-day university education, i.e., to the beginnings of modern graduate study and the emergence of new universities. Empirical statistics are given to substantiate the rapid growth of graduate study and of the number of degrees produced since the 1980s. The mean number of Ph.D. Degrees per year has increased from a few in a single university in the 1930s to nearly a hundred in today's twenty seven universities in Turkey in the 1980s. Finally, a quantitative overview of the growth trends in graduate study in basic sciences as well as an assessment of the present degree productivity of Turkish universities are presented.  相似文献

Purpose: The aim of this paper is to compare the extension services offered in the field of organic agriculture (OA) in Baden-Württemberg (BW), Germany and Crete, Greece.

Design/methodology approach: 16 in-depth interviews, 10 in BW and 6 in Crete, were carried out with representatives of OA extension providers; interviews were qualitatively analyzed and overall results compared between the two areas.

Findings: The structure along with extensionists' capacities and methods employed are rich, appropriate, and well functioning in BW. On the contrary, poor structure, lack of networking and facilitation in Crete jeopardizes extension performance and impact. Practical implications: Contrary to BW, the situation in Grete does not allow for much optimism concerning the successful development of OA and the implementation of European Innovation Partnerships.

Theoretical implications: Further elaboration of the characteristics of extension/advisory services and their interlinkages, including the role of the state in facilitating pluralistic services, is needed.

Originality/value: The paper demonstrates the importance of the structure of extension services and the central facilitation role of the state; furthermore, the interdependency of structure, capacity and the methods employed is demonstrated which, in turn, influences extension performance and impact especially networking and facilitation for social learning and innovation co-creation.  相似文献

A complete coverage of the course content does not lead the student to explorative curiosity and to a scientific attitude to knowledge and learning. Interactive hypermedia use will lead to an epistemological quality raising since in that way students’ independence in planning, knowledge acquisition and problem solving might be facilitated and since at the same time tutorial supervision and guidance can be included. Hypermedia have possibilities to provide students with large quantities of information. With network interfacing learning can take place independent of time and place and individualized education will be possible. Combined with CMC (computer mediated communication) and educational software the student has a tool for life-long education within the classroom. At the Växjö University text, images and simulations have been integrated within a hypertext system: Hyperbook (for Macintosh). At the Royal Institute of Technology we develop this concept to use it with computer-based self-study material in mechanics, a project which started in autumn 1990 using HyperCard. At the University of Lund a development of hypertext material in the form of computer illustrated text for a thermodynamics textbook has just started. An example of limits of models will be demonstrated by a computer simulation of a linearized and a non-linearized pendulum.  相似文献

This paper explores various kinds of logics of ‘business education for sustainability’ and how these ‘logics’ position the subject business person, based on eight teachers’ reasoning of their own practices. The concept of logics developed within a discourse theoretical framework is employed to analyse the teachers’ reasoning. The analysis takes its starting point in different approaches to how a business ought to or could take responsibility for sustainable development. Different approaches to business ethical responsibilities, in combination with assumptions about how educational content is legitimised and presupposed purposes of education, are used to construct logics of business education for sustainability. In the paper, the results of this analysis are presented as: the logic of profit-, social- or radical-oriented business education. Our results also show how the different logics position the subject business person differently, as one who adapts to, adds or creates ethical values. The results are first discussed in terms of how environmental and social challenges could be dealt with in the future and secondly, considering the risk of de-subjectification with regard to profit-oriented business education, the implications this may have for the educational quality itself.  相似文献

The study sought out to extend our knowledge regarding the origin of mathematical learning disabilities (MLD) in children by testing different hypotheses in the same samples of children. Different aspects of cognitive functions and number processing were assessed in fifth- and sixth-graders (11–13 years old) with MLD and compared to controls. The MLD group displayed weaknesses with most aspects of number processing (e.g., subitizing, symbolic number comparison, number-line estimation) and two cognitive functions (e.g., visual–spatial working memory). These findings favor the defective approximate number system (ANS) hypothesis, but do not fit well with the access deficit hypothesis. Support is also provided for the defective object-tracking system (OTS) hypothesis, the domain general cognitive deficit hypothesis and to some extent the defective numerosity-coding hypothesis. The study suggests that MLD might be caused by multiple deficits and not a single core deficit.  相似文献

The purpose of this study is to describe the strategies used by a mother with a child with autism during games activities with peers to provide the child with social skills. The research method of this study is ‘a qualitative single‐subject case study’. The participants in this research are a mother and her 9‐year‐old child with autism, one brother and three typically developing peers. The research data were collected through field notes, interviews, audio and videotape recordings during natural interactions between the mother and her child. The strategies the mother used were analysed using video records during games activities in a natural park. The interactions of the mother with her child were examined in the context of a hide‐and‐seek game. Micro‐ethnographic‐analysis techniques were used in the analysis of the video records. According to the research data, it was found that the mother with a child with autism made extensive use of 13 different verbal strategies and seven different non‐verbal strategies. It was observed that the mother guided her child and the group during the hide‐and‐seek game, arranged the environment of the games, carried out routine activities both at the beginning and at the end of the games and arranged the games in accordance with the abilities and preferences of the child. These applications bear a resemblance to the model of integrated game groups. As a result, the data from the present research reveal that a mother having a child with autism acts as a guide during the games and uses verbal and non‐verbal interaction strategies in this guidance process and by doing so contributes to the process of participation in the games by the child with autism and in the child's social interaction with his peers.  相似文献

Research has shown that early childhood science education is based on education and care, sometimes stressed as a dichotomy. The purpose of this study is to empirically investigate the relations between teachers' teaching and children's learning in preschool practice, both in terms of educative processes and nature-oriented content. The ambition is also to develop and present an analysis method that facilitates these investigations. Outdoor nature experiences of preschool children (aged one to three) were video-recorded, transcribed and analysed. The methodology is based on John Dewey's pragmatic philosophy. Here, epistemological move analysis (oriented towards teachers' guiding processes as moves) and substantive learning quality analysis (oriented towards multi-dimensional learning qualities) are developed and used as analysis tools. The analyses show that the relations between teaching and learning processes and nature content are intertwined and include education and care. The teachers guide towards aesthetical, moral, cognitive and physical qualities in learning by challenging, admonishing, instructional, confirming, generative, reorienting and reconstructing moves. The results contribute to nature-oriented teaching practice and nature-oriented preschool research when discussing and investigating teaching and learning processes and nature content.  相似文献
